Determination of aldicarb, propoxur, carbofuran, carbaryl and methiocarb residues in honey by HPLC with post-column derivatization and fluorescence detection after elution from a florisil column

The aim of this study was to develop an easy analytical method for determining aldicarb, propoxur, carbofuran, carbaryl and methiocarb residues in honey by high performance liquid chromatography with post-column derivatization and fluorescence detection (HPLC/PCD-FL) for routine analysis. A florisil packed column was used in sample preparation step and showed good performance. The recoveries ranged between 72.02 and 92.02% for various spiking levels (50, 100, 200 ng/g). The limits of detection were 4-5 ng/g, depending on different N-methylcarbamate pesticides. The extraction method used in the present study was easy, inexpensive, and rapid. Thus, it could be used efficiently in the routine monitoring studies.
